Chapter 18.5, Problem 3CP

Using data from Appendix 2, calculate $\Delta$ G° (in kJ/mol) at $\text{25°C}$ for the reaction:

${\text{CH}}_4(g){\text{ + 2O}}_{\text{2}}\text{(}g\text{) }\to {\text{ CO}}_{\text{2}}\text{(}g{\text{) + 2H}}_{\text{2}}\text{O(}g\text{)}$

$\begin{array}{l}\text{a)}\\ \text{-580}\text{.8 kJ/mol}\\ \text{b)}\\ 580.8\text{ kJ/mol}\\ \text{c)}\\ -572.0\text{ kJ/mol}\\ \text{d})\\ -800.8\text{ kJ/mol}\\ \text{e})\\ -818.0\text{ kJ/mol}\end{array}$
